Systems Of Nonlinear Wave Equations With Damping And Supercritical Sources, Yanqiu Guo
Systems Of Nonlinear Wave Equations With Damping And Supercritical Sources, Yanqiu Guo
Department of Mathematics: Dissertations, Theses, and Student Research
We consider the local and global well-posedness of the coupled nonlinear wave equations
utt – Δu + g1(ut) = f1(u, v)
vtt – Δv + g2(vt) = f2(u, v);
in a bounded domain Ω subset of the real numbers (Rn) with a nonlinear Robin boundary condition on u and a zero boundary conditions on v. The nonlinearities f1(u, v) and f2(u, v) are with supercritical exponents …
Global Well-Posedness For A Nonlinear Wave Equation With P-Laplacian Damping, Zahava Wilstein
Global Well-Posedness For A Nonlinear Wave Equation With P-Laplacian Damping, Zahava Wilstein
Department of Mathematics: Dissertations, Theses, and Student Research
This dissertation deals with the global well-posedness of the nonlinear wave equation
utt − Δu − Δput = f (u) in Ω × (0,T),
{u(0), ut(0)} = {u0,u1} ∈ H10 (Ω) × L 2 (Ω),
u = 0 on Γ × (0, T ),
in a bounded domain Ω ⊂ ℜ n with Dirichlét boundary conditions. The nonlinearities f (u) acts as a strong source, which is allowed to …
